United States Navy

The United States Navy (USN) is the branch of the United States armed forces responsible for naval operations. The U.S. Navy consists of 281 ships and over 4,000 aircraft. It has over half a million men and women on active or ready reserve duty. The United States Navy traces its origins to the Continental Navy, which the Continental Congress established during the American Revolutionary War. The United States Constitution, ratified in 1789, empowered Congress "to provide and maintain a navy." Acting on this authority, Congress ordered the construction and manning of six frigates; one of the original six, USS Constitution, familiarly known as "Old Ironsides," survives to this day. The War Department administered naval affairs from that year until Congress established the Department of the Navy on April 30, 1798. The Navy became part of the Department of Defense upon its establishment in 1947.

History of the Navy

Main article: History of the United States Navy History of the United States Navy The Continental Navy was established in Philadelphia by the Continental Congress on October 13, 1775, which authorized the procurement, fitting out, manning, and dispatch of two armed vessels to search for munitions ships supplying the British Army in America. The legislation also established a Naval Committee to supervise the work. The Continental Navy operated some 50 ships over the course of the American Revolutionary War, but no more than about 20 at one time. After the war, Congress sold the surviving ships and released the seamen and officers. Congress ordered the construction and manning of six frigates on March 27, 1794, and three years later welcomed into service the first three: USS United States, Constellation and Constitution. The frigates became famous in the War of 1812, where they unexpectedly defeated British Royal Navy forces several times. During the American Civil War, the Navy was an innovator in the use of ironclad warships, but after the war slipped into obsolescence. A modernization program beginning in the 1880s brought the U.S. into the first rank of the world's navies by the beginning of the 20th century. 20th century (middle) and USS Annapolis (SSN 760) (front)]] The Navy saw little action during World War I, but grew into a formidable force in the years before World War II. Japan unsuccessfully attempted to allay this strategic threat with a late-1941 surprise attack on Pearl Harbor. During the next three years, the U.S. Navy grew into the most powerful in the world. It is widely accepted that currently the United States Navy remains the most powerful in the world.

Organization

The Navy is administered by the Department of the Navy, led by the Secretary of the Navy (SECNAV). The senior naval officer, the Chief of Naval Operations (CNO), is the four-star admiral immediately under the Secretary of the Navy. The Secretary of the Navy and Chief of Naval Operations are responsible for organizing, recruiting, training, and equipping the Navy so the Navy is ready for operation under the command of the Unified Combatant Commanders. (Also see United States Armed Forces Organization.) President | SECDEF | ------------------- | | SECNAV | | | CNO Unified Combatant Commanders | | -------------------- | | | | Shore establishment Operating Forces (including fleets)

Fleets

The two main fleets are the Pacific Fleet and the Atlantic Fleet. Under these two organizations fall the numbered fleets.
- 1st Fleet - no longer active
- 2nd Fleet – Atlantic Ocean — Flagship Iwo Jima, Norfolk, Virginia
- 3rd Fleet – Eastern and Northern Pacific Ocean — Flagship Coronado, San Diego, California (In peacetime the Third Fleet has no ARG and the carriers in the area are either on their way to the Seventh Fleet or conducting training cruises, after an overhaul for example.)
- 4th Fleet – Disbanded.
- 5th Fleet – Middle East — Headquartered at Manama, Bahrain
- 6th Fleet – Mediterranean Sea — Flagship Mount Whitney, Gaeta, Italy
- 7th Fleet – Western Pacific and Indian Ocean — Flagship Blue Ridge, Yokosuka, Japan

Shore commands

In addition to afloat fleets, the Navy maintains several "Naval Forces Commands" which operate naval shore facilities and serve as liaison units to local ground forces of the Air Force and Army. Such commands are answerable to a Fleet Commander as the shore component of the afloat command. During times of war, all Naval Forces Commands augment to become task forces of a primary fleet. Some of the larger Naval Forces Commands include:
- Commander Naval Forces Korea (CNFK)
- Commander Naval Forces Marianas (CNFM)
- Command Naval Forces Japan (CNFJ)

Staff corps

In addition to the regular line commands of the navy, several staff corps are also maintained which augment the line community and whose personnel are assigned to both line and staff commands. The current staff corps of the United States Navy are as follows:
- Navy Supply Corps
- Navy Medical Corps
- Navy Medical Service Corps
- Navy Nurse Corps
- Navy Chaplains Corps
- Navy Civil Engineer Corps (Seabees)
- Navy Judge Advocate General (JAG)

Weapons

Ships

Main article: U.S. Navy ships See also List of ships of the United States Navy for a more complete listing of ships past and present. The names of commissioned ships of the U.S. Navy start with USS, meaning 'United States Ship'. Non-commissioned, civilian-manned vessels of the U.S. Navy have names that begin with USNS, standing for 'United States Naval Ship'. A letter-based hull classification symbol is used to designate a vessel's type. The names of ships are selected by the Secretary of the Navy. The names are usually those of U.S. states, cities, towns, important people, famous battles, fish, and ideals. The U.S. Navy pioneered the use of nuclear reactors aboard naval vessels; today, they power most U.S. aircraft carriers and submarines. See United States Naval reactor. As of January 2004, a relatively small number of ship classes accounted for the bulk of the U.S. naval fleet. These include:

Aircraft carriers

United States Naval reactor on November 3, 2003. Approximately fifty aircraft can be counted on deck.]] Aircraft carriers are the major strategic arm of the Navy. They put U.S. air power within reach of most land-based military power. The US Navy's carriers are much larger and more powerful than those of the rest of the world. See also: List of aircraft carriers of the United States Navy and List of escort aircraft carriers of the United States Navy. Modern aircraft carriers since CV-67 are typically named for living or dead politicians; previous aircraft carriers were named for battles and famous fighting ships of the Navy.
- Kitty Hawk class (1 ship)
- Enterprise — Norfolk, Virginia
- John F. Kennedy — Mayport Naval Station, Florida
- Nimitz class (9 ships, 1 under construction)
  - USS Nimitz (CVN-68)
  - USS Dwight D. Eisenhower (CVN-69)
  - USS Carl Vinson (CVN-70)
  - USS Theodore Roosevelt (CVN-71)
  - USS Abraham Lincoln (CVN-72)
  - USS George Washington (CVN-73)
  - USS John C. Stennis (CVN-74)
  - USS Harry S. Truman (CVN-75)
  - USS Ronald Reagan (CVN-76)
  - USS George H.W. Bush (CVN-77)

Amphibious assault ships

The largest of all amphibious warfare ships amphibious assault ships resemble small aircraft carriers; capable of V/STOL, STOVL, VTOL tiltrotor and rotary wing aircraft operations; contains a welldeck to support use of Landing Craft Air Cushion and other watercraft. Amphibious assault ships are typically named after World War II aircraft carriers, a name source kept over from the earliest ones, which were converted WWII carriers.
- Wasp class (7 ships)
- Tarawa class (4 ships active, 1 decommissioned)

Amphibious transport docks

Amphibious transports are warships that embark, transport, and land elements of a landing force for a variety of expeditionary warfare missions. Amphibious transport docks are named for cities, except for USS New York (LPD-21), which is named for the state of New York and USS Somerset (LPD-25), which is named for Somerset County, Pennsylvania.
- San Antonio class (3 launched, 2 under construction, 3 planned, 2 projected)
- Austin class (10 ships active, 1 Decommissioned, 1 converted to AGF)

Submarines

:Main article: Submarines in the United States Navy There are two major types of submarines, ballistic and attack. Ballistic subs have a single, strategic mission: carrying nuclear SLBMs. Attack submarines have several tactical missions, including sinking ships and subs, launching cruise missiles, and gathering intelligence. Sea attack submarines are typically named for cities; land attack submarines (Virginia and Ohio-class boats) are typically named for states. Earlier attack submarines were named for fish, while earlier ballistic missile submarines were named for "famous Americans" (although many of these were actually foreigners).
- Ohio class (18 in commission) — ballistic missile submarines, 4 to be converted into guided missile submarines
- Virginia class (1 in commission, 3 under construction, 2 on order) — attack submarines
- Seawolf class (3 in commission) — attack submarines
- Los Angeles Class (51 in commission) — attack submarines

Cruisers

Guided missile cruisers can conduct air warfare, surface warfare and undersea warfare. All modern cruisers are named for battles. Previous cruisers were either named for cities (until CG-12), the redesignated frigates were named for naval heroes (CG-15 to CG-35) or states (CG-36 to CG-42).
- Ticonderoga class (23 in commission) — first ships to carry the Aegis combat system

Destroyers

See also the List of destroyers of the United States Navy. All destroyers have been named for naval heroes since USS Bainbridge (DD-1).
- Arleigh Burke class (44 in commission as of June 2005) — first ship class with comprehensive design for stealth technology.

Frigates

Modern frigates mainly perform anti-submarine warfare and escort other ships. The U.S. Navy is gradually retiring its frigates; some of their jobs will be performed by the nascent littoral combat ship. [http://peoships.crane.navy.mil/lcs/] Named, like the destroyers, for naval heroes.
- Oliver Hazard Perry class (30 ships in commission)

Battleships

All U.S. battleships have been retired, although two Tomahawk-capable ships remain in "Inactive" Reserve. They are maintained in accordance with the National Defense Authorization Act of 1996. Current plans in the United States Navy call for keeping the battleships on the NVR until the naval surface fire support gun and missile development programs achieve operational capability, which is expected to occur sometime between 2003 and 2008. All battleships except USS Kearsarge (BB-5) were named for states.
- Iowa class

Early vessels


- USS Constitution — "Old Ironsides," oldest commissioned warship afloat
- USS Monitor — first US ironclad warship, also first rotating turret
- USS Merrimack — a wooden warship rebuilt by the Confederates as the ironclad CSS Virginia
- USS Alligator — the first submarine of the Civil War, but sunk while being towed during a storm.
- CSS Hunley — First submarine to sink a ship in a combat engagement, though it sunk in the aftermath as well. Built by the Confederates near the end of the Civil War. Sank USS Housatonic with a spar-mounted torpedo.

Harbor defense

The United States Navy has, in the last few years, greatly expanded its harbor defense forces in response to the War on Terrorism. The main components of Naval Harbor Defense include:
- Inshore Boat Units (IBUs)
- Mobile Inshore Undersea Warfare Units (MIUWUs)
- Special Boat Units (SBUs)

Special warfare

The Navy Seals are the U.S. Navy's primary special warfare units whose purpose is to engage in "special activities other than war". The Navy also maintains an EOD Corps (Explosive Ordnance Disposal) as well as a small corps of Surface Warfare personel known by the designator "Special Operations Underway".

Submarine warfare and nuclear deterrence

The submarine has a long history in the USN. It began in the late 19th century, with the building of the SS-1, USS Holland. The boat was in service for 10 years and was a developmental and trials vessel for many systems on other early submarines. The submarine really came of age in World War I. The USN did not have a large part in this war, with its action mainly being confined to escorting convoys later in the war and sending a division of battleships to reinforce the British Grand Fleet. However, there were those in the USN submarine service who saw what the Germans had done with their U-boats and took careful note. Doctrine in the inter-war years emphasised the submarine as a scout for the battle fleet, and also extreme caution in command. Both these axioms were proven wrong after the attack on Pearl Harbor in December 1941. The submarine skippers of the fleet boats of World War II waged a very effective campaign against Japanese merchant vessels, doing to Japan what Germany failed to do to the United Kingdom. They were aggressive and effective, and operated far from the fleet. In addition to their commerce raiding role, submarines also proved valuable in air-sea rescue. There was many an American aircraft carrier pilot who owed his life to the valour of USN submarine crews, including future U.S. President George H. W. Bush.

Navy revolutions

After WWII, things continued along much the same path until the early 1950s. Then a revolution, that was to forever change the nature of the submarine arm occurred. That revolution was USS Nautilus. The Nautilus was the first nuclear-powered submarine. Up until that point, submarines had really been, at their most basic level, torpedo boats that happened to be able to go underwater. They had been tied to the surface by the need to charge their batteries using diesel engines relatively often. The nuclear power plant of the Nautilus meant that the boat could stay underwater for literally months at a time, the only limit in the end being the amount of food that the boat could carry. Another revolution in submarine warfare came with USS George Washington. Nuclear powered, like Nautilus, George Washington added strategic ballistic missiles to the mix. Earlier submarines had carried strategic missiles, but the boats had been diesel powered, and the missiles required the boat to surface in order to fire. The missiles were also cruise missiles, which were vulnerable to the defences of the day in a way that ballistic missiles were not. George Washington's missiles could be fired whilst the boat was submerged, meaning that it was far less likely to be detected before firing. The nuclear power of the boat also meant that, like Nautilus, George Washington's patrol length was only limited by the amount of food the boat could carry. Ballistic missile submarines, carrying Polaris missiles, eventually superseded all other strategic nuclear systems in the USN. Deterrent patrols continue to this day, although now with the Ohio class boats and Trident missiles. Trident missile]] Given the lack of large scale conventional naval warfare since 1945, with the USN's role being primarily that of power projection, the submarine service did not fire weapons in anger for very many years. The development of a new generation of cruise missiles changed that. The BGM-109 Tomahawk missile was developed to give naval vessels a long range land attack capability. Other than direct shore bombardment, and strikes by aircraft flying off carriers, the ability of naval vessels to influence warfare on land was limited. Now, instead of being limited to firing shells less than 20 miles inland from guns, any naval vessel fitted with the Tomahawk could hit targets up to 1,000 miles inland. The mainstay of the Tomahawk equipped vessels in the early days of the missile's deployment were the Iowa class battleships, and the submarine fleet. The Tomahawk was first used in combat on 17 January 1991, on the opening night of Operation Desert Storm. On that day, for the first time since the surrender of Japan in 1945, an American submarine fired in combat, when Tomahawks were launched by US boats in the eastern Mediterranean. Since then, the Tomahawk has become a staple of American campaigns. It has seen use in no less than three separate wars. It has also been exported to the United Kingdom, which has also fitted it to submarines. The Tomahawk has seen a change in the design of attack submarines. At first it was fired through torpedo tubes, but more recent US boats have been fitted with vertical launch systems to enable them to carry more of the weapons. In the early 21st century, the USN submarine fleet is made up entirely of nuclear powered vessels. It is the most powerful of its type in the world. However, there are those who worry that there are not enough boats in the fleet. As with other branches of the US military the budget cuts of the late 1980s and the early 1990s, as the Cold War ended, followed up by the War on Terrorism, have left little or no slack in the system. This point is illustrated by the fact that in 2003, for the first time since 1945, a US submarine made two back-to-back war patrols.

Personnel

Commissioned officer

Commissioned officers in the Navy have paygrades from O-1 to O-10. Officers with superior performance may be promoted. Officers between O-1 and O-4 are called junior officers, O-5 and O-6 are called senior officers, and O-7 to O-10 are called flag officers. See U.S. Navy officer rank insignia for a complete list of paygrades and corresponding ranks. Commissioned officers belong to one of the following communities:
- Unrestricted line: Surface Warfare, Aviation Warfare, Submarine Warfare, Special Warfare, Nuclear
- Restricted line: Engineering Duty, Aerospace Engineering Duty, Aerospace Maintenance Duty, Cryptologic, Naval Intelligence, Public Affairs, Meteorology and Oceanography, Information Professional, Human Resource
- Staff Corps: Supply Corps, Medical Corps, Medical Service Corps, Dental Corps, Nurse Corps, Chaplain Corps, Civil Engineer Corps, Judge Advocate General Corps, Navy Band Corps The term "line" officer means someone who may command a warship or an aviation unit. It is a carryover from the 18th-century British tactic of employing warships in a "line" to take advantage of cannons on each side of the ship. The captains of such vessels commanded "ships of the line." Today, all Navy line officers wear a star on the sleeves of uniforms near the cuff braid that denotes rank. Staff officers wear different insignias. Note: Marine Corps officers, also part of the Department of the Navy, are all considered "line" officers because they are qualified as troop commanders in addition to their specialties. Commissioned officers originate from the United States Naval Academy, Navy Reserve Officer Training Corps (NROTC), Officer Candidate School (OCS), direct commission, and other commissioning programs (such as [https://www.sta-21.navy.mil/ Seaman to Admiral-21] and Limited Duty Officer programs).

Enlisted

Enlisted members of the Navy have paygrades from E-1 to E-9. Enlisted members with superior performance may be advanced in paygrade. Two notably significant advancements are Seaman to Petty Officer Third Class (E-3 to E-4) and Petty Officer First Class to Chief Petty Officer (E-6 to E-7). Advancement to Chief Petty Officer is especially significant, marked by a special initiation ceremony. See U.S. Navy enlisted rate insignia for a complete list of the paygrades. All new active-duty enlisted members receive basic training ("boot camp") at the Recruit Training Command in Great Lakes, Illinois. Those who have a contract for a specific rating continue onto "A" schools for training in the rating. Those who don't have a specific rating go into the fleet to learn on the job and later strike for a rating. Some members may go to additonal training in a "C" school either before a tour of duty, or after a tour of duty. A "C" school assigns a member a Navy Enlisted Classification code, or NEC, which shows that a sailor is able to perform a specific task requiring that NEC, such as NEC 2780 - Network Security Vulnerablity Technician. Enlisted members of paygrades E-4 and above are said to be "rated" and have a rating: an occupational specialty. As of June 2005, there are more than 50 ratings, including Boatswain's Mate, Quartermaster, Engineman, Damage Controlman, Electronics Technician, Information Systems Technician, Air Traffic Controller, Fire Control Technician, Gunner's Mate, Sonar Technician, Construction Mechanic, Hospital Corpsman, Yeoman, Disbursing Clerk, Culinary Specialist, Photographer's Mate, Musician, Master-at-Arms, Aviation Electronics Technician, and Cryptologic Technician. Some ratings have subspecialties acquired either through an initial "A" school for training (such as Cryptologic Technician Technical and Cryptologic Technician Collection) or through a separate "C" school (such as Aviation Electronics Technician Organizational and Aviation Electronics Technician Intermediate.)

Qualifications

Sailors prove they have mastered skills and deserve responsibilities by completing Personal Qualification Standards (PQS) tasks and examinations. Among the most important is the "warfare qualification," which denotes a journeyman level of capability in Aviation Warfare, Special Warfare, Surface Warfare, or Submarine Warfare. Many qualifications are denoted on a sailor's uniform with U.S. Navy badges and insignia.

Sea Warrior

Launched in 2003 as part of the Navy's [http://www.chinfo.navy.mil/navpalib/cno/proceedings.html Sea Power 21] transformation plan, Sea Warrior is intended to link the fleet's personnel processes (recruiting, training, and assigning) with acquisition processes (buying ships, aircraft, etc.) in a way that also improves each individual sailor's ability to guide his or her own career in a satisfying direction. The aim is to more efficiently muster the right number of sailors with the right skills and seniority at each ship, squadron, and duty station. Sea Warrior is led by the Chief of Naval Personnel[http://www.chinfo.navy.mil/navpalib/people/flags/biographies/hoewinggl.html], and the commander of the [https://www.cnet.navy.mil/netc/netc.html Naval Education and Training Command].

Naval culture

Navy sailors are trained in the core values of Honor, Courage, Commitment. Sailors cope with boredom on long cruises of six months to a year, and cherish their time in their home ports, as well as vacations at ports abroad.

Naval jack

Chief of Naval Personnel Chief of Naval Personnel Chief of Naval Personnel The naval jack of the United States is the First Navy Jack, first used during the American Revolutionary War. On May 31, 2002, Secretary of the Navy Gordon England directed all U.S. naval ships to fly the First Navy Jack for the duration of the War on Terrorism. Many ships chose to shift colors on September 11, 2002. The jack is flown from the bow of the ship and the ensign from the stern when the ship is moored or anchored. When underway, the ensign is flown from the main mast. The former naval jack was a blue field with 50 white stars, identical to the canton of the ensign, both in appearance and size. A jack of similar design was first used in 1794, though with 13 stars arranged in a 3–2–3–2–3 pattern.

Naval jargon

Main article: Military slang A distinct jargon has developed among sailors over the course of the last four centuries. Naval jargon is spoken by American sailors as a normal part of their daily speech. There are three distinct components of Naval jargon:
- Words that are unique to sailing and have no use in standard English, such as yardarm, bow, and stern.
- Archaic English that remains common in naval jargon, such as "aye" (the common English word for "Yes" until the 16th century), "Fo'c'sle" (from Fore Castle), and Bo'sun (from "Boat Swain", swain being Middle English for a young man or a servant).
- Modern jargon, such as "Bird" to refer to missiles, or 1MC. See U.S. Navy slang for more information. Also see Covey Crump.

United States

:For alternative meanings, see the disambiguation page for US, USA, United States, or American. The United States of America is a federal democratic republic situated primarily in central North America. It comprises 50 states and one federal district, and has several territories. It is also referred to, with varying formality, as the United States, the U.S., the U.S.A., the States, or simply and most commonly, America. The official founding date of the United States is July 4, 1776, when the Second Continental Congress—representing thirteen British colonies—adopted the Declaration of Independence. However, the structure of the government was profoundly changed in 1788, when the states replaced the Articles of Confederation with the United States Constitution. The date on which each of the fifty states adopted the Constitution is typically regarded as the date that state "entered the Union" (became part of the United States). Since the mid-20th century, following World War II, the United States has emerged as a dominant global influence in economic, political, military, scientific, technological, and cultural affairs.

Geography and climate

The United States shares land borders with Canada (to the north) and Mexico (to the south), and territorial water boundaries with Canada, Russia, the Bahamas, and numerous smaller nations. It is otherwise bounded by the Pacific Ocean and the Bering Sea, in the west; the Arctic Ocean, in the northernmost areas; and the Atlantic Ocean, the Gulf of Mexico, and the Caribbean Sea, in the eastern and southeastern areas. Forty-eight of the states are in the single region between Canada and Mexico; this group is referred to, with varying precision and formality, as the continental or contiguous United States, sometimes abbreviated CONUS, and as the Lower 48. Alaska, which is not included in the term contiguous United States, is at the northwestern end of North America, separated from the Lower 48 by Canada. The archipelago of Hawaii is in the Pacific Ocean. The capital city, Washington, District of Columbia is a federal district located on land donated by the state of Maryland. (Virginia also donated land, but it was returned in 1847.) The United States also has overseas territories with varying levels of independence and organization. When inland water is included in the total area, only Russia and Canada are larger than the United States; if inland water is excluded, China ranks third and the U.S. ranks fourth. The United States' total area is 3,718,711 square miles (9,631,418 km²), of which land makes up 3,537,438 square miles (9,161,923 km²) and water makes up 181,273 square miles (469,495 km²). The United States' landscape is one of the most varied among those of the world's nations: among its many features are temperate forestland and rolling hills, on the east coast; mangrove, in Florida; the Great Plains, in the center of the country; the Mississippi–Missouri river system; the Great Lakes, four of the five of which are shared with Canada; the Rocky Mountains, west of the Great Plains; deserts and temperate coastal zones, west of the Rocky Mountains; and temperate rain forests, in the Pacific northwest. Alaska's tundra, and the volcanic, tropical islands of Hawaii add to the geographic diversity. Hawaii The climate varies along with the landscape, from tropical in Hawaii and southern Florida to tundra in Alaska and atop some of the highest mountains. Most of the North and East experience a temperate continental climate, with warm summers and cold winters. Most of the South experiences a subtropical humid climate with mild winters and long, hot, humid summers. Rainfall decreases markedly from the humid forests of the Eastern Great Plains to the semi-arid shortgrass prairies on the high plains abutting the Rocky Mountains. Arid deserts, including the Mojave, extend through the lowlands and valleys of the southwest, from westernmost Texas to California and northward throughout much of Nevada. Some parts of California have a Mediterranean climate. Rainforests line the windward mountains of the Pacific Northwest from Oregon to Alaska.

History

American history started with the migration of people from Asia across the Bering land bridge approximately 12,000 years ago following large animals that they hunted into the Americas. These Native Americans left evidence of their presence in petroglyphs, burial mounds, and other artifacts. It is estimated that 2-9 million people lived in the territory now occupied by the U.S. before European contact, and the subsequent introduction of foreign diseases such as small pox that greatly diminished the native populations. Some advanced societies were the Anasazi of the southwest, who inhabited Chaco Canyon, and the Woodland Indians, who built Cahokia, located near present-day St Louis, a city with a population of 40,000 at its peak in AD 1200. Vikings first visited North America around 1000, but did not settle permanently. Following the discovery voyages of Christopher Columbus around 1492, other Europeans began to explore and settle there. During the 1500s and 1600s, the Spanish settled parts of the present-day Southwest and Florida, founding St. Augustine, Florida in 1565 and Santa Fe (in what is now New Mexico) in 1607. The first successful English settlement was at Jamestown, Virginia, also in 1607. Within the next two decades, several Dutch settlements, including New Amsterdam (the predecessor to New York City), were established in what are now the states of New York and New Jersey. In 1637, Sweden established a colony at Fort Christina (in what is now Delaware), but lost the settlement to the Dutch in 1655. This was followed by extensive British settlement of the east coast. The British colonists remained relatively undisturbed by their home country until after the French and Indian War, when France ceded Canada and the Great Lakes region to Britain. Britain then imposed taxes on the 13 colonies, widely regarded by the colonists as unfair because they were denied representation in the British Parliament. Tensions between Britain and the colonists increased, and the thirteen colonies eventually rebelled against British rule. British Parliament, George Washington (1789-1797).]] In 1776, the 13 colonies split from Great Britain and formed the United States, the world's first constitutional and democratic federal republic, after their Declaration of Independence of that year, and the Revolutionary War (1775 to 1783). The original political structure was a confederation in 1777, ratified in 1781 as the Articles of Confederation. After long debate, this was supplanted by the Constitution in 1789, forming a more centralized federal government. Prior to all these was the Albany Congress in 1754, in which a union was first seriously proposed. From early colonial times, there was a shortage of labor, which encouraged unfree labor, particularly indentured servitude and slavery. In the mid-19th century, a major division occurred in the United States over the issue of states' rights and the expansion of slavery. The northern states had become opposed to slavery, while the southern states saw it as necessary for the continued success of southern agriculture and wanted it expanded to the territories. Several federal laws were passed in an attempt to settle the dispute, including the Missouri Compromise and the Compromise of 1850. The dispute reached a crisis in 1861, when seven southern states seceded1 from the Union and formed the Confederate States of America, leading to the Civil War. Soon after the war began, four more southern states seceded. During the war, Abraham Lincoln issued the Emancipation Proclamation, mandating the freedom of all slaves in states in rebellion, though full emancipation did not take place until after the end of the war in 1865, the dissolution of the Confederacy, and the Thirteenth Amendment took effect. The Civil War effectively ended the question of a state's right to secede, and is widely accepted as a major turning point after which the federal government became more powerful than state governments. Thirteenth Amendment). The title of the painting, from a 1726 poem by Bishop Berkeley, was a phrase often quoted in the era of Manifest Destiny, expressing a widely held belief that civilization had steadily moved westward throughout history. [http://americanart.si.edu/t2go/1lw/1931.6.1.html (more)] ]] During the 19th century, many new states were added to the original 13 as the nation expanded across the continent. Manifest Destiny was a philosophy that encouraged westward expansion in the United States. As the population of the Eastern states grew and as a steady increase of immigrants entered the country, settlers moved steadily westward across North America. In the process, the U.S. displaced most American Indian nations. This displacement of American Indians continues to be a matter of contention in the U.S. with many tribes attempting to assert their original claims to various lands. In some areas American Indian populations were reduced by foreign diseases contracted through contact with European settlers, and US settlers acquired those emptied lands. In other instances American Indians were removed from their traditional lands by force. Though some would say the U.S. was not a colonial power until the Spanish-American War when it acquired Puerto Rico, Guam and the Philippines, the dominion exercised over land in North America the United States claimed is essentially colonial. The Philippines became independent in 1946. During this period, the nation also became an industrial power. This continued into the 20th century, which has been termed "the American Century" because of the nation's overriding influence on the world. The US became a center for innovation and technological development; major technologies that America either developed or was greatly involved in improving include the telephone, television, computer, the Internet, nuclear weapons, nuclear power, aviation, and aeronautics. In addition to the Civil War, another major traumatic experience for the nation was the Great Depression (1929 to 1939). The nation has also taken part in several major foreign wars, including World War I and World War II (in both of which the US later joined the Allies). During the Cold War, the US was a major player in the Korean War and Vietnam War, and, along with the Soviet Union, was considered one of the world's two "superpowers". With the collapse of the Soviet Union, the US emerged as the world's leading economic and military power. Beginning in the 1990s, the United States became very involved in police actions and peacekeeping, including actions in Kosovo, Haiti, Somalia and Liberia, and the first Persian Gulf War driving Iraq out of Kuwait. After attacks on the World Trade Center and the Pentagon on September 11, 2001, the United States and other allied nations found themselves involved in what has come to be called the "War on Terrorism," which has primarily encompassed military actions in both Afghanistan and Iraq.

Government

Iraq of the United States.]]

Republic and suffrage

The United States is an example of a constitutional republic, with a government composed of and operating through a set of limited powers imposed by its design and enumerated in the United States Constitution. Specifically, the nation operates as a presidential democracy. There are three levels of government: federal, state, and local. Officials of each of these levels are either elected by eligible voters via secret ballot or appointed by other elected officials. Americans enjoy almost universal suffrage from the age of 18 regardless of race, sex, or wealth. There are some limits, however: felons are disenfranchised and in some states former felons are likewise. Furthermore, the national representation of territories and the federal district of Washington, DC in Congress is limited: residents of the District of Columbia are subject to federal laws and federal taxes but their only Congressional representative is a non-voting delegate.

Federal government

The federal government is the national government, comprising the Legislative Branch (led by Congress), the Executive Branch (led by the President), and the Judicial Branch (led by the Supreme Court). These three branches were designed to apply checks and balances on each other. The Constitution limits the powers of the federal government to defense, foreign affairs, the issuing and management of currency, the management of trade and relations between the states, and the protection of human rights. In addition to these explicitly stated powers, the federal government—with the assistance of the Supreme Court—has gradually extended these powers into such areas as welfare and education, on the basis of the "necessary and proper" clause of the Constitution.

The Congress

necessary and proper The Congress of the United States is the legislative branch of the federal government of the United States. It is bicameral, comprising the House of Representatives and the Senate. The House of Representatives consists of 435 members, each of whom represents a congressional district and serves for a two-year term. House seats are apportioned among the states by population; in contrast, each state has two Senators, regardless of population. There are a total of 100 senators, who serve six-year terms. The powers of Congress are limited to those enumerated in the Constitution; all other powers are reserved to the states and the people. The Constitution also includes the necessary-and-proper clause, which grants Congress the power to "make all laws which shall be necessary and proper for carrying into execution the foregoing powers."

The President

necessary-and-proper clause At the top level of the executive branch is the President of the United States. The President and Vice-President are elected as 'running mates' for four-year terms by the Electoral College, for which each state, as well as the District of Columbia, is allocated a number of seats based on its representation (or ostensible representation, in the case of D. C.) in both houses of Congress (see U.S. Electoral College). The relationship between the President and the Congress reflects that between the English monarchy and parliament at the time of the framing of the United States Constitution. Congress can legislate to constrain the President's executive power, even with respect to his or her command of the armed forces; however, this power is used only very rarely—a notable example was the constraint placed on President Richard Nixon's strategy of bombing Cambodia during the Vietnam War. The President cannot directly propose legislation, and must rely on supporters in Congress to promote his or her legislative agenda. The President's signature is required to turn congressional bills into law; in this respect, the President has the power—only occasionally used—to veto congressional legislation. Congress can override a presidential veto with a two-thirds majority vote in both houses. The ultimate power of Congress over the President is that of impeachment or removal of the elected President through a House vote, a Senate trial, and a Senate vote. The threat of using this power has had major political ramifications in the cases of Presidents Andrew Johnson, Richard Nixon, and Bill Clinton. The President makes around 2,000 executive appointments, including members of the Cabinet and ambassadors, which must be approved by the Senate; the President can also issue executive orders and pardons, and has other Constitutional duties, among them the requirement to give a State of the Union address to Congress once a year. Although the President's constitutional role may appear to be constrained, in practice, the office carries enormous prestige that typically eclipses the power of Congress: the Presidency has justifiably been referred to as 'the most powerful office in the world'. The Vice President is first in the line of succession, and is the President of the Senate ex officio, with the ability to cast a tie-breaking vote. The members of the President's Cabinet are responsible for administering the various departments of state, including the Department of Defense, the Justice Department, and the State Department. These departments and department heads have considerable regulatory and political power, and it is they who are responsible for executing federal laws and regulations. George W. Bush is the 43rd President, currently serving his second term.

The Courts

George W. Bush The highest court is the Supreme Court, which consists of nine justices. The court deals with federal and constitutional matters, and can declare legislation made at any level of the government as unconstitutional, nullifying the law and creating precedent for future law and decisions. Below the Supreme Court are the courts of appeals, and below them in turn are the district courts, which are the general trial courts for federal law. Separate from, but not entirely independent of, this federal court system are the individual court systems of each state, each dealing with its own laws and having its own judicial rules and procedures. A case may be appealed from a state court to a federal court only if there is a federal question; the supreme court of each state is the final authority on the interpretation of that state's laws and constitution.

State and local governments

supreme court of each state. Note that Alaska and Hawaii are shown at different scales, and that the Aleutian Islands and the uninhabited Northwestern Hawaiian Islands are omitted from this map.]] The state governments have the greatest influence over people's daily lives. Each state has its own written constitution and has different laws. There are sometimes great differences in law and procedure between the different states, concerning issues such as property, crime, health, and education. The highest elected official of each state is the Governor. Each state also has an elected legislature (bicameral in every state except Nebraska), whose members represent the different parts of the state. Of note is the New Hampshire legislature, which is the third-largest legislative body in the English-speaking world, and has one representative for every 3,000 people. Each state maintains its own judiciary, with the lowest level typically being county courts, and culminating in each state supreme court, though sometimes named differently. In some states, supreme and lower court justices are elected by the people; in others, they are appointed, as they are in the federal system. The institutions that are responsible for local government are typically town, city, or county boards, making laws that affect their particular area. These laws concern issues such as traffic, the sale of alcohol, and keeping animals. The highest elected official of a town or city is usually the mayor. In New England, towns operate directly democratically, and in some states, such as Rhode Island and Connecticut, counties have little or no power, existing only as geographic distinctions. In other areas, county governments have more power, such as to collect taxes and maintain law enforcement agencies.

Political divisions

With the Declaration of Independence, the thirteen colonies proclaimed themselves to be nation states modeled after the European states of the time. Although considered as sovereigns initially, under the Articles of Confederation of 1781 they entered into a "Perpetual Union" and created a fully sovereign federal state, delegating certain powers to the national Congress, including the right to engage in diplomatic relations and to levy war, while each retaining their individual sovereignty, freedom and independence. But the national government proved too ineffective, so the administrative structure of the government was vastly reorganized with the United States Constitution of 1789. Under this new union, the continued status of the individual states as sovereign nation states fell into dispute in 1861, as several states attempted to secede from the union; in response, then-President Abraham Lincoln claimed that such secession was illegal, and the result was the American Civil War. Since the Union victory in 1865, the independent status of the individual states has not been broached again by any state, and the status of each state within the union has been deemed by mainstream officials and academics to be settled as being subordinate to the union as a whole. In subsequent years, the number of states grew steadily due to western expansion, the purchase of lands by the national government from other nation states, and the subdivision of existing states, resulting in the current total of 50. The states are generally divided into smaller administrative regions, including counties, cities and townships. The United States–Canadian border is the longest undefended political boundary in the world. The U.S. is divided into three distinct sections:
- the "continental United States," also known as "the Lower 48" and more accurately termed the conterminous, coterminous or contiguous United States
- Alaska, which is physically connected only to Canada
- the archipelago of Hawaii, in the central Pacific Ocean. The United States also holds several other territories, districts, and possessions, notably the federal district of the District of Columbia, which is the nation's capital, and several overseas insular areas, the most significant of which are American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the United States Virgin Islands. The Palmyra Atoll is the United States' only incorporated territory; it is unorganized and uninhabited. The United States Navy has held a base at a portion of Guantanamo Bay, Cuba, since 1898. The United States government possesses a lease to this land, which only mutual agreement or United States abandonment of the area can terminate. The present Cuban government of Fidel Castro disputes this arrangement, claiming Cuba was not truly sovereign at the time of the signing. The United States argues this point moot because Cuba apparently ratified the lease post-revolution, and with full sovereignty, when it cashed one rent check in accordance with the disputed treaty.

Foreign relations and military

sovereign] The immense military and economic dominance of the United States has made foreign relations an especially important topic in its politics, with considerable concern about the image of the United States throughout the world. Reactions towards the United States by other nationalities are often strong, ranging from uninhibited admiration and mimicking of all things American to anti-Americanism. US foreign policy has swung about several times over the course of its history between the poles of strict isolationism and imperialism and everywhere in between. Three of the nation's four military branches are administered by the Department of Defense: the Army, the Navy (including the Marine Corps), and the Air Force. The Coast Guard falls under the jurisdiction of the Department of Homeland Security in peacetime, but is placed under the Department of the Navy in time of war. The combined United States armed forces consist of 1.4 million active duty personnel, along with several hundred thousand each in the Reserves and the National Guard. Military conscription ended in 1973. The United States Armed forces are considered to be the most powerful military (of any sort) on Earth and their force projection capabilities are unrivaled by any other nation. The 2005 defense budget amounted to $401.7 billion, which is an increase of 4% over 2004 and of 35% since 2001. Over 50% of that number is spent in research & development. (For comparison, in 2004 the European Union (considered as the second-largest military force) had a combined total of 1.6 million troops, and a defense budget of €160 billion, with less than 10% of that being spent on R&D.)

Largest cities

The United States has dozens of major cities, including 11 of the 55 global cities of all types — with three "alpha" global cities: New York City, Los Angeles, and Chicago. The figures expressed below are for populations within city limits. A different ranking is evident when considering U.S. metro area populations, although the top three would be unchanged. Note that some cities not listed (such as Atlanta, Boston, Las Vegas, Miami, Nashville, New Orleans, Seattle, and Washington, D.C.) are still considered important on the basis of other factors and issues, including culture, economics, heritage, and politics. The twenty largest cities, based on the United States Census Bureau's 2004 estimates, are as follows:

Economy

The United States has the largest single-country economy in the world, with a per-capita gross domestic product of $40,100. In this market-oriented economy, private individuals and business firms make most of the decisions, and the federal and state governments buy needed goods and services predominantly in the private marketplace. gross domestic product The largest industry of the U.S. is now service, which employs roughly three quarters of the U.S. work force. The United States has many natural resources, including oil and gas, metals, and such minerals as gold, soda ash, and zinc. In agriculture, the U.S. is a top producer of, among other crops, corn, soy beans, and wheat; the United States is a net exporter of food. The U.S. manufacturing sector produces goods such as, cars, airplanes, steel, and electronics, among many others. Economic activity varies greatly from one part of the country to another, with many industries being largely dependent on a certain city or region; New York City is the center of the American financial, publishing, broadcasting, and advertising industries; Silicon Valley is the country’s primary location for high-technology companies, while Los Angeles is the most important center for film production. The Midwest is known for its reliance on manufacturing and heavy industry, with Detroit, Michigan, serving as the center of the American automotive industry; the Great Plains are known as the "breadbasket" of America for their tremendous agricultural output; the intermountain region serves as a mining hub and natural gas resource; the Pacific Northwest for fish and timber, while Texas is largely associated with the oil industry; the Southeast is a major hub for both medical research and the textiles industry. Several countries continue to link their currency to the dollar or even use it as a currency (such as Ecuador), although this practice has subsided since the collapse of the Bretton Woods system. Many markets are also quoted in dollars, such as those of oil and gold. The dollar is also the predominant reserve currency in the world, and more than half of global reserves are in dollars. The largest trading partner of the United States is Canada (19%), followed by China (12%), Mexico (11%), and Japan (8%). More than 50% of total trade is with these four countries. In 2003, the United States was ranked as the third most visited tourist destination in the world; its 40,400,000 visitors ranked behind France's 75,000,000 and Spain's 52,500,000. Labor unions have existed since the 19th century, and grew large and powerful from the 1930s to the 1950s. See Labor history of the United States. Since 1970 they have shrunk in the private sector and now cover fewer than 8% of the workers. However union membership has grown rapidly in the public sector, especially among teachers, nurses, police, postal workers, and municipal clerks. There have been few strikes in recent years. The United States' imports exceed exports by 80%, leading to an annual trade deficit of $700,000,000,000, or 6% of gross domestic product. It is the largest debtor nation in the world, with total gross foreign debt of over $13,000,000,000,000 (2005 estimate); and it absorbs more than 50% of global savings annually. Since the 1980s, the U.S. has increased the use of neoliberal economic policies that reduce government intervention and reduce the size of the welfare state, backing away from the more interventionist Keynsian economic policies that had been in favor since the Great Depression. As a result, the United States provides fewer government-delivered social welfare services than most industrialized nations, choosing instead to keep its tax burden lower and relying more heavily on the free market and private charities. Sixteen states and the District of Columbia have minimum wages higher than the national level ($5.15 per-hour), including the highest, Washington State at $7.35. Twenty-six states are the same as the federal level; two--Ohio and Kansas--are below; and six do not have state laws. America's wealth is relatively highly concentrated. The average C.E.O. earns 500 times the typical amount a worker grosses, this is up from 25 times in the late 1970s. In terms of wealth the top 1% of Americans own 40% of all assets and 50.1% of the country's income goes to the top twenty percent of households. Average wages for the majority of employees have been largely stagnating since the 1970s. America's poverty line defined as a family of four earning less than $19,157 is at 12.7% of the general population. Approximately one out of every five children in the United States grows up below the official poverty line. Among racial groups; African Americans have the lowest median income while Asians had the highest. Regionally, the southern states had the lowest median incomes while the West Coast and New England had the highest. The current Federal Reserve Chairman Alan Greenspan remarked that the U.S.’s growing income inequality since the 1970s is, "not the type of thing which a democratic society - a capitalist democratic society - can really accept without addressing."[http://www.csmonitor.com/2005/0614/p01s03-usec.html?s=itm] However, Greenspan also noted, "...you can look at the system and say it's got a lot of problems to it, and sure it does. It always has. But you can't get around the fact that this is the most extraordinarily successful economy in history."

Transportation

Alan Greenspan ]] Because the United States is a relatively young nation, most of the development of U.S. cities has taken place since the invention of the automobile. To link its vast territory, the United States built a network of high-capacity, high-speed highways, of which the most important element is the Interstate Highway system, commissioned in the 1950s by President Dwight D. Eisenhower and modeled after the German Autobahn. The United States also has a transcontinental rail system, which is used for moving freight across the lower forty-eight states. Passenger rail service is provided by Amtrak, which serves forty-six of the lower forty-eight states. Many cities in the United States have extensive mass-transit systems. New York City operates one of the world's largest and most heavily used subway systems. The regional rail and bus networks that extend into Long Island, New Jersey, Upstate New York, and Connecticut are among the most heavily used in the world. Air travel is often preferred for destinations over 300 miles (500 kilometers) away. In terms of passengers, seventeen of the world's thirty busiest airports in 2004 were in the U.S., including the world's busiest, Hartsfield-Jackson Atlanta International Airport; in terms of cargo, in the same year, twelve of the world's thirty busiest airports were in the U.S., including the world's busiest, Memphis International Airport. There are several major seaports in the United States; the three busiest are the Port of Los Angeles, California; the Port of Long Beach, California; and the Port of New York and New Jersey. Others include Houston, Texas; Charleston, South Carolina; Savannah, Georgia; Miami, Florida; Portland, Oregon; San Francisco, California; Boston, Massachusetts; Philadelphia, Pennsylvania; and Seattle, Washington; plus, outside the contiguous forty-eight states, Anchorage, Alaska, and Honolulu, Hawaii.

Demographics

Hawaii The mean center of the U.S. population continues to drift farther west and south. The fastest growing region is the western United States followed by the southern portion. According to Census 2000, the states that saw the greatest increases from 1990 were: Nevada (66.3%), Arizona (40%), Colorado (30.6%), Utah (29.6%), Idaho (28.5%), Georgia (26.4%), Florida (23.5%), Texas (22.8%), North Carolina (21.4%), and Washington (21.1%). [http://www.census.gov/population/cen2000/phc-t2/tab03.pdf]

Ethnicity and race

:Main article: Racial demographics of the United States The United States is a very racially diverse country. According to the 2000 census, it has 31 ethnic groups with at least one million members each, and numerous others represented in smaller amounts. The majority of Americans descend from white European immigrants who arrived at the establishment of the first colonies (most after Reconstruction). This majority--69.1% in 2000--decreases each year, and is expected to become a plurality within a few decades. The most frequently stated European ancestries are German (15.2%), Irish (10.8%), English (8.7%), Italian (5.6%) and Scandinavian (3.7%). Many immigrants also hail from Slavic countries such as Poland and Russia. Other significant immigrant populations came from eastern and southern Europe and French Canada. Russia Hispanics from Mexico and South and Central America are the largest minority group in the country, comprising 12.5% of the population (2000 census). People of Mexican descent made up 7.3% of the population in the 2000 census, and this proportion is expected to increase significantly in the coming decades. About 12.3% (2000 census) of the American people are African Americans (Blacks). African Americans are spread throughout the country, but their presence is largest in the South. Asian Americans--including Native Hawaiians and Pacific Islanders--are a third significant minority (3.7% of the population in 2000). Most Asian Americans are concentrated on the West Coast and Hawaii. The largest groups are immigrants or descendants of emigrants from the Philippines, China, India, Vietnam, South Korea, and Japan. Indigenous peoples in the United States, such as American Indians and Inuit, make up 0.9% of the population (2000 census). About 35% live on Indian reservations.

Religion

Polls estimate that just under 80 percent of Americans are Christians of various denominations. The other 20 percent comprises other religions such as Hinduism, Judaism, Islam, and Buddhism, other various faiths, and those without a specific religion. The United States is noteworthy among developed nations for its relatively high level of religiosity. According to a 2004 Gallup poll, about 44% of Americans attend a religious service at least once a week. However, this rate is not uniform across the country; attendance is more common in the Bible Belt—composed largely of Southern and Midwestern states—than in the Northeast and West Coast. In the Southern states, Baptists are the largest group, followed by Methodists; Roman Catholics are dominant in the Northeast and in large parts of the Midwest due to their being settled by descendants of Catholic immigrants from Europe (such as Germany, Ireland, Italy, and Poland) or other parts of North America (mainly Quebec and Puerto Rico). The rest of the country for the most part has a complex mixture of various Christian groups.

Education

West Coast's home at Monticello and the University of Virginia (library building shown above, and designed by Jefferson), the only collegiate campus on the list. Both sites are located in Charlottesville, Virginia.]] In the United States, education is a state, not federal, responsibility, and the laws and standards vary considerably. However, the federal government, through the Department of Education, is involved with funding of some programs and exerts some influence through its ability to control funding. In most states, all students must attend mandatory schooling starting with kindergarten, which children normally enter at age 5, and following through 12th grade, which is normally completed at age 18

- United States Coast Guard Approximately 1.4 million personnel are currently on active duty in the military with an additional 860,000 personnel in the seven reserve components (456,000 of which are in the Army and Air National Guard). There is currently no conscription. The armed forces are also members of the United States Uniformed Services. The United States Armed Forces is the most powerful military in the world and their power projection capabilities are unrivaled by any other singular nation (e.g. People's Republic of China, Russia, India) or organization (e.g. the European Union). The United States Department of Defense is the controlling organization for the U.S. military and is headquartered at The Pentagon. The Commander-in-Chief of the U.S. military is the President of the United States. The United States military is a hierarchical military organization, with a system of military ranks to denote levels of authority within the organization. The military service is divided into a professional officer corps along with a greater number of enlisted personnel who perform day-to-day military operations. The United States officer corps is not restricted by social class or nobility, but is by college education. United States military officers are appointed from a variety of sources, including the service academies, ROTC, and direct appointment from both civilian status and the enlisted ranks. The U.S. military also maintains a number of military awards and badges to denote the qualifications and accomplishments of military personnel. On July 26, 1948 U.S. President Harry S. Truman signed Executive Order 9981 which racially desegregated the military of the United States. Homosexuals, however, are still barred from serving openly (see Don't ask, don't tell.) By law, women may not be put into direct combat; however, asymmetrical warfare has put women into situations which are direct combat operations in all but name. (Approximately 9% of Army positions available; see [http://www.goarmy.com/JobDetail.do?id=47] as an example).
